Like others here I have the Mac Pro + Lion = Won't sleep on its own issue so I took the advice of a poster to reset my PRAM and NVRAM. After my machine booted up I noticed my CPU was at 99% and my temps hitting 70c! I check activity monitor to find DMPROXY had 4 instances open all using 99% of my CPU. I manually forced closed them but I have no idea what would cause this to happen as I've never seen this happen before. If anyone has insight on this I'd be most appreciative.
